TMNT: The Last Ronin - The Lost Years #4A (IDW Publishing 2023)

Dive into issue 4A of the 2023 IDW Publishing series, which delivers a complete 32-page full-color narrative rated M while splitting the TMNT: The Last Ronin - The Lost Years saga across two interconnected timelines. Written by franchise co-creator Kevin Eastman alongside long-time collaborator Tom Waltz, this installment expands the alternate-unverse lore with tight, dual-tracking plotting that appeals to both longtime mutants fans and readers exploring the mature-rated Last Ronin branch for the first time.

In the past timeline, Michaelangelo’s quest for vengeance halts abruptly upon capture and imprisonment. He is thrust into a global gladiatorial circuit where survival requires relentless combat. The issue tracks his transition from isolated fighter to reluctant ally, highlighting brutal arena encounters and the uneasy truces that form when mutual reliance outweighs rivalry. Every match advances his ultimate goal of breaking free to face the source of his torment.

Parallel to those events, the narrative shifts forward to a fractured near-future New York City. Casey Marie Jones assumes a teaching role, guiding a small group of newly trained turtles through the tactical and ethical foundations laid by their late companion. As urban infrastructure collapses and hostile forces gain ground, the issue emphasizes disciplined strategy, adaptive problem-solving, and the psychological weight of operating without institutional support.

Interior artwork alternates between Ben Bishop and SL Gallant, each bringing distinct pacing and atmospheric depth to the contrasting settings, while SL Gallant handles the exterior cover layout. The script maintains a consistent 32-page comic book format optimized for standard single-issue collectors, ensuring smooth readability whether purchased standalone or collected into archival editions.
